Add/Update would update a field or create new if it existed, but didn't
allow for creating new if the field existed.
This patchset splits the options to 'Add & Update' so that 'Add' will always
add a field and 'Update' will operate as it always has
To test:
1 - Have a record with a known existing field (make a copy)
2 - Define a marc modification template that 'Add/update' on that field
3 - Define an 'Add/Update' on a field that doesn't exist
4 - Batch modify the copy of record using the above template
5 - Verify the existing field was updated
6 - Verify the non-existing field was updated
7 - Apply patch and update database
8 - Make another copy
9 - Modify the copy with the same template as above
10 - Should match initial modification
11 - Add a new rule to add a new field
12 - Modify using the updated template
13 - Ensure your new field is created
14 - Test various options in the modification tool
15 - prove t/db_dependent/MarcModificationTemplates.t
